What is the first line of treatment for periapical abscess?

Amoxicillin is still the first-line drug of choice but with 34% of Prevotella species resistant to amoxicillin, the alternatives of amoxicillin/clavulanate, clindamycin, and metronidazole need to be considered.

What is a periapical lucency?

Periapical lucencies are often seen incidentally at head and neck imaging studies performed for indications not related to the teeth. These lesions are, however, occasionally manifestations of diseases that have a wide range of effects and may at times represent the source of symptoms that prompted the study.

What causes a periapical abscess?

A periapical tooth abscess occurs when bacteria invade the dental pulp — the innermost part of the tooth that contains blood vessels, nerves and connective tissue. Bacteria enter through either a dental cavity or a chip or crack in the tooth and spread all the way down to the root.

What are 5 typical antibiotics used in dentistry?

What Are The Antibiotics Used In Dentistry?

• Amoxicillin.
• Azithromycin.
• Cephalexin.
• Clindamycin.
• Penicillin.

Does lucency mean infection?

Although the majority of periapical lucencies seen on radiographs and computed tomographic images occur secondary to apical periodontal or pulpal disease, not all lucencies near the tooth root are due to infection.

What is lucency mean?

Lucency meaning (medicine) A pale area revealed in radiography, computed tomography, or similar examination technique.

How do you describe periapical abscess?

A periapical abscess is a collection of pus at the root of a tooth, usually caused by an infection that has spread from a tooth to the surrounding tissues.

What causes periapical lucency?

These lesions are, however, occasionally manifestations of diseases that have a wide range of effects and may at times represent the source of symptoms that prompted the study. The vast majority of periapical lucencies are the result of apical periodontal or pulpal disease.

How are radiographic and Histological evaluation of persistent periapical lesions?

Aim: To determine the histology of persistent periapical lesions associated with nonsurgical endodontic treatment failures and to compare radiographically the sizes of periapical lesions and the presence or absence of the radiopaque lamina with the histological findings.

What are the radiographic features of a periapical granuloma?

Periapical granuloma (Fig 3), cyst (Fig 4), and abscess (Fig 5) represent a spectrum of the same pathologic process and are difficult to distinguish from one another radiographically. The shared radiographic features include a lucent halo surrounding the tooth root, often with caries of the affected tooth.

How is cone beam CT used to diagnose periapical disease?

Cone-beam CT provides detailed anatomy of the teeth and bones and can be used to evaluate periapical lesions in multiple planes, thus allowing improved detection and anatomic delineation of disease (13 – 15). However, it has poor soft-tissue contrast resolution and is therefore not ideal for evaluation of extraosseous lesions (11, 12).

What kind of biopsy is used to diagnose abscess?

Biopsy specimens were obtained during apical microsurgery and examined under light microscopy by oral pathologists. Histological analysis established diagnoses of granuloma, cyst, abscess and scar tissue.
